I'm on KE 653 ICN-BKK on April 9, KE 654 BKK-ICN on April 16. Visiting for Songkran.
Looks like you'll be the first to report back about the 773, bostonbali. I've heard the A333 is the worst widebody in KE's fleet for pitch and seat quality. I think you're right, brahms77, that you'll be a little tired when you get to PUS.
